and
IMMEDIATE
switches cause the controller to keep
unflushed data in the write-back cache until it restarts and is able to write the
data to devices. Do not perform any hardware changes and do not let the cache
batteries run down before the controller can flush the cache.
____________________________________________________________
IGNORE_ERRORS
NOIGNORE_ERRORS (Default)
The IGNORE_ERRORS and NOIGNORE_ERRORS switches instruct the the
controller how to respond to write-back cache errors.
_________________________ Caution ___________________________
The IGNORE_ERRORS switch may cause data to remain in write-back cache.
____________________________________________________________
Specify IGNORE_ERRORS to instruct the controller to ignore any write-back cache
errors. Such errors can result from data contained within write-back cache that cannot be
written to the devices or lost data errors.
Specify NOIGNORE_ERRORS to instruct the controller not to run the self-test program if
write-back cache errors are detected.
